Meta and Inria's Stable Signature bakes invisible watermarks into AI models
Meta FAIR and Inria just open-sourced Stable Signature, a new watermarking method for open-source AI image generators. Instead of slapping watermarks on exported images, it roots an invisible signature directly inside the model's decoder, making it survive cropping, compression, and ControlNet fine-tuning. Why it matters: it virtually eliminates false positives while tracing deepfakes straight back to the model that made them.
